Jake, I started the car sunday with the new induction configuration and I thought I left the mufflers off as it was louder than I had ever noticed before, and I never spun the rpm over 2000 since I didnt have my timing light to check total timing and rotor phase.

fenderwell headers 3'' into 12'' bullet mufflers turn downs in front of rear wheels.......what ...what .....WHAT !!!!!!....not for the faint at heart....we wore ear plugs last year...... im going to have new mufflers this year.....

I ran 3 inch pipe into 2 chamber Flowmasters for Dragweeks 06 thru 08. Then changed to 2 1/2 inch pipe and Dynomax Ultraflo Welded mufflers. The car became much quieter at road speeds and the gas mileage increased. Since my Camaro only has 302 cubic inches, it is necessary to remove the exhaust when on the track. Removal is worth a min of at least 3 tenths!

Case size is the key to quiet, the bigger the case for a given length and inlet/outlet diameter the quieter it'll be in almost any brand. It will also be heavier.

That's what it's all about....big mufflers are quieter than small mufflers. And you want the outlet way in the back, away from your ears.

Single 3 inch exhaust through a Magnaflow that splits into two 2 1/2 inch tailpipes that have two Vibrant resonators. Nice and quiet. Electronic cut out at the right front fender if I want to be loud.

Not if its after a Turbo

[LAGNAF]

Do you really need any mufflers after a turbo??

seems like they quiet the exhaust down a ton by themselves!!

I'm going to try a set of these:

Dynomax VT. Has a flapper valve that makes them quiet when cruising but opens up for free flow at WOT. Sort of like the 'vette does with its flapper valve.

I had a Moroso spiroflow set up on my car, had to wear ear plugs until I lined the car with HVAC duct insulation:

Finally got it really quiet inside when I extended the exhaust tip all the way back past the bumper.

It was quiet inside but still set off every honda/acura alarm when I'd pull through a parking lot. LOL

I can set off car alarms with mine....... I love that!!!

My neighbor says it is weird........my car isn't loud, but the depth of the noise and the resonance shakes the soffets on the house when I drive by.

Yea, my truck does the same.. it's really effective cuz the exhaust exits out the sides. So when you drive by a car, or especially in a covered parking, it will set off EVERY cars alarm!!

If you put the muffs at the rear bumper it will make it quieter... as the gasses get cooler
they reduce in volume(area) and is much easier to control the note... plus it has less
back pressure... I worked in the Fuel& Exhaust lab at Chrysler for 35 years and did tons
of testing... if you notice now days the muffs on most new cars is back as far as possible
to gain a few things... more HP due to the lesser back pressure and its easier to control
the sound
